ModelNode declares constants ModelNode.TRUE, ModelNode.FALSE, ModelNode.ZERO and ModelNode.ZERO_LONG. Save memory and a bit of runtime cost by using these instead of the hundreds of 'new ModelNode(true)' etc.

This kind of thing does the trick for me:

find ~/dev/wildfly/wildfly -type f -name "*.java" -exec grep -i "new ModelNode(false)" -l {} \; -exec sed -i "" 's/new ModelNode(false)/ModelNode.FALSE/g' {} \;
